Microsoft in on the multi-touch act...
"Surface Computing has Arrived" Microsoft Surface !!!
In a combination of many of the different touch techniques I've talked about before Microsoft have produced a beautiful marketing piece for multi-touch surfaces.
The marketing goodness cleverly uses the gestures of the multi-touch UI as the animated tramnsitions in the Flash promo material very, very smart.
As well as multi-touch they also show the use of physical tokens like Reactable and talk about "phones practical introduce themselves"; a social network of devices just as Bill Buxton told us was coming.
Update: Nad's found a nice launch video
